The techniques presented herein relate to automatic network address translation (NAT) discovery and traverse for edge devices in a software-defined network in a wide area network (SD-WAN). More specifically, the techniques presented herein relate to techniques for automatic, symmetric NAT discovery and traverse between SD-WAN edge devices that ensure new branches can become part of an SD-WAN overlay network without explicit user (e.g., customer/administrator) involvement. Accordingly, and advantageously, the techniques presented herein can dynamically provide NAT-T hub connectivity for symmetric devices that can be used for service insertion of NAT-T functions. These techniques may vastly simplify SD-WAN deployment in diverse deployments and, thus, may provide significant business value.
